Minimum load requirement of up to 10% of the Working Load Limit to ensure the operation of the braking system. E.g. a 1.5 tonne lever block requires a minimum load of 150kg.

Light loading; not suitable for tandem operations. If one of the lever blocks used in the tandem experiences an increase in the shared load and the other is reduced below the minimum load, inoperative breaks may occur and this could cause for the load to fall. For these applications we recommend the Vital Lever Blocks VR-2 series below.

Vital Lever Blocks VR-2 series

The VR-series lever blocks feature a “lock-in and lock-out” braking system which is the more traditional style with a free-wheeling system requiring the disengagement of the gear drive mechanism which is impossible with any load suspended on it.

These lever blocks are ideally suited for the (underground) mining, aerospace and energy industries.

Manufactured in Japan using optimum high quality steel which conforms to the strict JIS & ISO regulations.

All Vital models are manufactured to comply with AS1418.2.

Vital lever blocks can be supplied with overload protection for added security of use (excluding 250kg and 500kg models).

The unique design of the bottom hook prevents slipping and ensures safe operation.

Encapsulated needle bearings and side plate bearings for smoother operation.

Brake lockout bearing for security of braking mechanism.

All Pacific lever blocks can be supplied with overload protection (except 250kg).

Key internal components are CNC machined before being heat-treated and toughened.

Fitted with high quality European zinc plated Grade 80 load chain.

No aluminum content which ensures suitability for mining applications.

Overall better design and improved finish to prolong life expectancy.

Beaver Lever Blocks

Heavy duty, available up to 9 tonne capacity, the V-Series industrial manual lever block is designed for a variety of applications in mining, heavy industry, major construction works and off shore exploration.

The V-Series Lever Block has all the features of the Beaver 3G lever blocks, with extra safety built into its design.

The load chain is made of high resistance, Grade 80 Alloy Steel, black finish, heat treated, calibrated and marked according to Australian standard of AS1418.2.

Incorporating a safety overload clutch (limiter) mechanism, an added safety precaution, as the handle cuts out at around 30% more than the rated W.L.L. to prevent severe overloading of the lever block.

Each 3G-V Chain Lever Block is operationally tested to its rated capacity and is supplied with a Beaver test certificate, relating to its stamped identification side plate.
